New York Classic 6C Trumpet Mouthpiece Inner rim diameter: 6 - 16.70mm It feels similar to a Bach 3-5, with a cup depth around C-B. There are a few minor scratches, but it's generally in good condition. The box is also included. This is a reproduction mouthpiece from a manufacturer that has enjoyed high popularity in New York for many years, across various genres. Production began using original data and manufacturing tools held by an American manufacturer. Because it is made faithfully to the original blueprints, the sound, response, and playing feel are all the same as the vintage mouthpieces.
